garagemethods Posted February 10, 2009 Report Share Posted February 10, 2009 i plan on deleting the cat and getting a wheatley tune to by pass the rear o2 sensor. but when i have inspection and i bolt the cat back in how will my truck run with the wheatley tune and the cat back on?

Krambo Posted February 10, 2009 Report Share Posted February 10, 2009 There will be hardly a difference if the only update to your tune is deleting the code. Could screw with your fuel trims a bit but not to worry IMHO...your still running a MAF tune correct? Quote Link to comment Share on other sites More sharing options...
garagemethods Posted February 10, 2009 Author Report Share Posted February 10, 2009 its the stock tune. no tune yet. so when i do put the cat back in to get inspected it won't change much? Quote Link to comment Share on other sites More sharing options...
mcmahan Posted February 10, 2009 Report Share Posted February 10, 2009 just delete them, your tune from wheatley may make the truck pass inspection. i had a 02 camaro ss i deleted the cats tuned it with hp tuners then had to go for inspection/emissions test it passed with flying colors Quote Link to comment Share on other sites More sharing options...
70chevy03ss Posted February 10, 2009 Report Share Posted February 10, 2009 I have high flow cats into a dual magnaflow muffler the thing is load and I pass everytime.. Now all they do is plug the truck in if you don't throw a code your all set Quote Link to comment Share on other sites More sharing options...
blackss461982 Posted February 17, 2009 Report Share Posted February 17, 2009 have you talked to wheatley to see if his version of hptuners will support your year vehicle? not sure if yours will be any diff from ours as far as inspection but as long as they don't look you should be cool and if they do i have a frined that works at an inspection place and will pass you NO mater what Quote Link to comment Share on other sites More sharing options...
